You must configure VRRP on both MC-LAG peers for both the active and standby members to accept and route packets. Additionally, you must configure the VRRP backup device to send and receive ARP requests.
If you are using the VRRP over IRB or RVI method to enable Layer 3 functionality, you must configure static ARP entries for the IRB or RVI interface of the remote MC-LAG peer to allow routing protocols to run over the IRB or RVI interfaces.
Starting in Junos OS Release 15.2R1, you do not need to configure a static ARP or ND entry for the remote IRB IP address. If you have already manually configured a static ARP or ND entry and upgrade to a later release, the static entry is deleted when ICCP goes down. If you configured ICCP on the IRB static entry, then ICCP might not come up. As a workaround, you can disable the automatic creation of static ARP and ND entries by issuing the following command:
